What were the first two great continents in continental drift
Pangea, the last supercontinent formed some 360 million years ago by the grouping of all existing continental masses, begins to separate 130 million later, during the transit between the Permian and Triassic, and it does so by fragmenting into two major continents:
One, which begins to drift north and is called Laurasia, and another, which drifts south, called Gondwana. These two great continental masses are separated by the Neotethys ocean.
Laurasia will subsequently fragment and give rise to what will be Eurasia and North America, while the rest of the continents will separate from Gondwana: South America, Africa, Antarctica and Indoaustralia, which in turn will break, giving rise to the Indian and Australian subcontinents.
